ORIGIN

This 1988 Porsche 911 Turbo was first sold in Massachusetts, moved to Illinois in 1994, and remained in the Chicago area with the seller after purchase in November 2004. He eventually relocated to Northern California in 2015 and has modified the car with several performance upgrades. Work has included a rebuild of the 4-speed gearbox with a Guard close-ratio gear set and limited-slip differential in 2008, and upgrades to the suspension and brake systems. The turbocharged flat-six was rebuilt in 2015 with an increase in displacement to 3.4-liters, ported and polished heads and injector blocks, flame ring cylinders, stroker crank, 964 cams, Garrett ball bearing turbocharger, Kokeln intercooler, and custom exhaust. A refurbished interior is equipped with a bolt-in half roll cage, sport seats, aftermarket steering wheel, and Wevo shifter. Now showing 131k miles, this 930 is offered with service records from 2004, a Carfax report, and a California title in the seller’s name.

The car is finished in black and has received paintwork under previous and current ownership. The driver’s side door and rear quarter panel were refinished in 2005 and the front lower valance, hood, and fenders in 2008 due to rock chips. The seller notes evidence of paintwork on other panels from prior owners. A RUF front valance with fog lights and a front-mounted RUF oil cooler were fitted in September 2005, with the seller describing the fit of the grille insert as less than perfect.

A set of 17″ Fikse FM5 wheels featuring black centers and wearing Nitto NT01 tires were installed in 2015. The windshield washer reservoir originally located in the driver-side front wheel well was removed to provide additional clearance under load for the larger front wheels and tires. The front windshield was replaced in May 2016, while the rear window seal is puckering at the corners.

The original leather interior has been replaced with black vinyl sport seats, lightweight door panels, and RS-style carpets. The rear seats have been removed and a bolt-in half roll cage has been installed. The Recaro seats seen in on-track photographs are not included in the sale.

An Alcantara MOMO steering wheel, exposed Wevo shifter with aluminum shift knob, and aluminum foot rests have been added. Factory air conditioning equipment has been removed from the car. The 6-digit odometer indicates approximately 131k miles, with the seller adding 32k during his 14 years of ownership.

The turbocharged flat-six was rebuilt, modified to 3.4 liters, and tuned by S-Car-Go Racing of San Rafael, California in 2015. Work included porting and polishing the cylinder heads, manifold, and injector blocks as well as machining of the cylinders, pistons, and connecting rods. The crank was cross drilled and polished, and the engine sheet metal, fan, shroud, and other items were bead blasted and repainted. Additional modifications include a Kokeln intercooler, TiAL wastegate, and Billy Boat headers feeding a custom exhaust system.

The videos above have been provided by the seller and show a start up as well as the engine idling and revving.

The 4-speed manual gearbox was rebuilt with a Guard close-ratio gear set and Pro 4340 chromoly limited-slip differential, while the clutch was replaced with a RUF CTR kit with aluminum flywheel. The clutch is noted as shuddering when the car is hot and stuck in traffic. The seller states that the car would be unlikely to pass a California emissions check due to a number of missing emissions components.

The stock suspension has been replaced with an updated performance setup that includes Elephant Racing and Wevo components. Cross-drilled brake rotors are reportedly due for replacement. The car weighs approximately 2,800 lb. according to the seller, and is capable of producing over 500 horsepower depending on boost setting.

The Carfax shows no accidents or other damage. A “Not Actual Mileage” title was issued in 1995 by Illinois, with a correction to the record noted in May 2014. Over 50 pages of records dating to the seller’s purchase in 2004 have been compiled in a service log and are said to total more than $70k.
